Current area of 4800 square meters, double the 9600 series
Let W = width of the new path
New length is 80 + 2W new width and is 60 + W
So:
(60 + W) (80 + 2 W) = 9600
2V ^ 2 + 200 + 4800 = W 9600 or W ^ 2 + 100W - 2400 = 0
The last equation can be taken into account (W 120) (W-be taken 20)
Thus, the width is 20 meters
